Tsubomi Kido is the very first member of the Mekakushi Dan and currently the leader of the group. She is often mistaken as a male due to her rather ambiguous tomboy-ish appearance. Although naturally kind in nature, she is short-tempered and easily gets angry even the smallest things.

She possesses the “Concealing Eyes” wherein it gives her the ability to conceal and hide her presence, as well as the presence of anyone within a two-meter radius.
